LOCK OR GUARD FOR WHI IELS OF VEHICLES.

SPECIFICATION forming part of Letters Patent No. 599,848, dated March 1, 1898.

Application filed May 21, 1897. Serial No. 637,510. (No model.)

In the holes 0 are placed the bolts 0 5 and thus hold the coupling against turning which are of about the same diameter as the upon the fork or frame. If the bar of the stud or boss 0, and in the outer holes 6 of fork or frame to which the .lock or guard is the guard-arm are placed a series of tumblers attached be of irregular or polygonal outline, f that are retained in position by shoul- 50 a corresponding shape will be given to the ders e at the outer ends of the holes e.

hen the guard-arm is in the locked position, (shown by dotted lines in Fig. 1 of the drawings,) the holes 0, e, and 0 will be coincident, and the coil-springsf will have forced the boltsf into the adjacent ends of the holes 0 of the stud or boss, thereby shifting the bolts c and causing these bolts to enter the adjacent ends of the holes 6. Hence it will be seen that the guard-arm E will be securely retained in locked position, and while in such position the wheel A of the vehicle cannot be turned.

It will be observed that the tumblers f within the holes c are of different lengths, and consequently to simultaneouslyforce inward all the bolts it will be necessary to employ a key G, having arms g corresponding to the difference in the lengths of the tumblers \Vhen the guard-arm is to be released, the arms 1 of the key G will be inserted into the holes 6 and the tumblersf will be forced inward, thereby depressing the bolts c and the bolts f until the bolts 0 are entirely within the holes c of the stud or boss C and until the boltsf are entirely within the holes 0, and when the bolts are thus depressed the guard-arm E can be turned to the unlocked position. (Shown by full lines in Fig. 1 of the drawings.) It will be understood, of course, that by varying the lengths of the tumblers f the character of the keys can be correspondingly varied, so that no two locks can be operated by the same key.

In order to retain the key G normally in place and in readiness for use, I prefer to form the key G with an opening g, through which will pass the end it of a spring-latch II, that is connected by a screw h to an angular arm C that projects from and is formed in piece with the coupling C. Hence it will be seen that when the guard-arm E is turned from the locked position shown by dotted lines to the unlocked position shown by full lines in Fig. 1 the end it of the spring-latch will pass through the opening g of the key, and the shoulder at the end of the spring-latch will securely retain the key with its arms g in position within the hole 6' of the guard-arm. \Vhen the guard-arm E is to be turned from the unlocked to the locked position, the spring-arm II will be raised, so that its end will pass from engagement with the key G. It will thus be seen that the spring-arm II not only retains the key in position, but also serves to hold the guard-arm in its unlocked position.

I wish it distinctly understood that while I have described what I regard as the preferred embodiment of my invention various changes in the details of construction inay be made by the skilled mechanic without departing from the spirit of the invention, and I do not wish the invention therefore to be understood as restricted to the precise details of construction shown.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. A look or guard comprising a support having means whereby it maybe attached to a part of the vehicle-frame, a boss or stud projecting from said support, a guard-arm provided with a hub encircling said boss or stud and provided with a chambered offset at one side of said hub and means for locking said hub to said boss or stud, substantially as described.

2. A lock or guard comprising a support provided with means whereby it may be attached to the vehicle-frame, a chambered boss or stud projecting from said support, a guard-arm provided with a hub for encircling said boss or stud and with a chambered offset at one side of said hub, and a series of bolts and tumblers for locking said guardarm to said boss or stud, openings being formed in the offset to admit a key for controlling said tumblers, substantially as described.

3. A look or guard comprising a support provided with means whereby it may be attached to the vehicle-frame, a guard-arm pivotally connected to said support and having a free end adapted to enter between the spokes of a Wheel, lock mechanism interposed between said guard-arm and the support, a key for controlling said lock mechanism and a latch for engaging the key and retaining it within the lock when the guard-arm is in unlocked position, substantially as described.

4. A lock or guard comprising a support provided with means whereby it may be attached to the vehicle-frame, a guard-arm pivotally connected to said support and having a free end adapted to enterbetween the spokes of a wheel, lock mechanism interposed between said guard-arm and the support, a key for controlling said lock mechanism and a spring-latch for engaging the key and retaining it within the look when the guard-arm is in unlocked position, substantially as described.

5. A lock or guard comprising a support provided with means whereby it may be attached to the vehicle-frame, a guard-arm pivotally connected to said support and having a free end adapted to enter between the spokes of the wheel, an offset on said guard-arm provided with openings to receive a key, a key provided with an opening adapted to receive a latch and a spring-actuated latch mounted upon the support and arranged to engage the opening in the key and retain the key within the lock when the guard-arm is in unlocked position, substantially as described.
